<div>&nbsp;dC 在秒了BZOJ 上所有的数论题后，感觉萌萌哒，想出了这么一道水题，来拯救日益枯</div>
<div>竭的水题资源。&nbsp;</div>
<div>&nbsp; 给定一个长度为 n的正整数序列A，有q次询问，每次询问一段区间内所有元素乘积的</div>
<div>&phi;（&phi;(n)代表1~n 中与n互质的数的个数） 。由于答案可能很大，所以请对答案 mod 10^6 +&nbsp;</div>
<div>777。 （本题强制在线，所有询问操作的l,r都需要 xor上一次询问的答案 lastans，初始时，</div>
<div>lastans = 0）&nbsp;</div>
</div>
<p></p></p><hr/><h3>输入格式</h3><p><p>&nbsp;第一行，两个正整数，N，Q，表示序列的长度和询问的个数。&nbsp;</p>
<div>第二行有N 个正整数，第i个表示Ai.&nbsp;</div>
<div>下面Q行，每行两个正整数，l r，表示询问[l ^ lastans,r ^ lastans]内所有元素乘积的&phi;&nbsp;</div></p><hr/><h3>输出格式</h3><p><p>Q行，对于每个询问输出一个整数。&nbsp;</p></p><hr/><h3>样例输入</h3><pre>5 10
